Objectives: It is well-known that post-traumatic stress disorder (PTSD) among firefighters contributes to their job-related stress. However, the relationship between burnout and PTSD in firefighters has rarely been studied. This study therefore explored the association between burnout and its related factors, such as trauma and violence, and PTSD symptoms among firefighters in Korea. Methods: A total of 535 firefighters participated in the Firefighter Research on Enhancement of Safety & Health study at 3 university hospitals from 2016 to 2017. The 535 participants received a baseline health examination, including questionnaires assessing their mental health. A Web-based survey was also conducted to collect data on job-related stress, history of exposure to violence, burnout, and trauma experience. The associations among burnout, its related factors, and PTSD symptoms were investigated using structural equation modeling. Results: Job demands (${\beta}=0.411$, p<0.001) and effort-reward balance (${\beta}=-0.290$, p<0.001) were significantly related to burnout. Burnout (${\beta}=0.237$, p<0.001) and violence (${\beta}=0.123$, p=0.014) were significantly related to PTSD risk. Trauma (${\beta}=0.131$, p=0.001) was significantly related to burnout; however, trauma was not directly associated with PTSD scores (${\beta}=0.085$, p=0.081). Conclusions: Our results show that burnout and psychological, sexual, and physical violence at the hands of clients directly affected participants' PTSD symptoms. Burnout mediated the relationship between trauma experience and PTSD.

Purpose: The purpose of this study was to use meta-analysis to evaluate the variables related to depression in patients who have had a stroke. Methods: The materials of this study were based on 16 variables obtained from 26 recent studies over a span of 10 years which were selected from doctoral dissertations, master's thesis and published articles. Results: Related variables were categorized into sixteen variables and six variable groups which included general characteristics of the patients, disease characteristics, psychological state, physical function, basic needs, and social variables. Also, the classification of six defensive and three risk variables group was based on the negative or positive effect of depression. The quality of life (ES=-.79) and acceptance of disability (ES=-.64) were highly correlated with depression in terms of defensive variables. For risk variables, anxiety (ES=.66), stress (ES=.53) showed high correlation effect size among the risk variables. Conclusion: These findings showed that defensive and risk variables were related to depression among stroke patients. Psychological interventions and improvement in physical functions should be effective in decreasing depression among stroke patients.

Purpose: The purpose of this study was to examine the relationship between perceived job stress and work environmental factors related with socioeconomics factors and physical burden in the golf caddies. Methods: Job stress in golf caddies was estimated by using the Karasek's job content questionnaire (JCQ) and work environmental factors were estimated by self-reported questionnaire and interview. Results: The subjects were 316 woman caddies who had never been occupationally exposed to hazardous chemicals, was mean age 31.1 years. Mean work duration was 6.44 years and working hours per day on low- and high-demand season were 6.16 and 10.51, respectively. The golf caddies displayed higher scores of job stress due to multiple factors such as working hours and frequency of rounding per week, physical burden, confliction, income satisfaction and employment stability. We found that high strain group was positive correlation with age, career, working hour (including frequency of rounding) and job demand, however, showed negative correlation with job decision latitude and support of supervisor and coworker. Conclusion: In conclusion, we suggest that the golf caddies be regard divided into high strain group as appropriate. Thus, stress management and health promotion program for golf caddies should be developed.

Increased oxidative stress in obese diabetes may have causal effects on diabetic complications, including dyslipidemia. Lipopolysccharides (LPS) along with an atherogenic diet have been found to increase oxidative stress and insulin resistance. Cranberry has been recognized as having beneficial effects on diseases related to oxidative stress. Therefore, we employed obese diabetic animals treated with an atherogenic diet and LPS, with the aim of examining the effects of cranberry powder (CP) on diabetic related metabolic conditions, including lipid profiles, serum insulin and glucose, and biomarkers of oxidative stress. Forty C57BL/KsJ-db/db mice were divided into the following five groups: normal diet + saline, atherogenic diet + saline, atherogenic diet + LPS, atherogenic diet + 5% CP + LPS, and atherogenic diet + 10% CP + LPS. Consumption of an atherogenic diet resulted in elevation of serum total cholesterol and atherogenic index (AI) and reduction of high density lipoprotein (HDL)-cholesterol. However, with 10% CP, the increase in mean HDL-cholesterol level was close to that of the group with a normal diet, whereas AI was maintained at a higher level than that of the group with a normal diet. LPS induced elevated serum insulin level was lowered by greater than 60% with CP (P < 0.05), and mean serum glucose level was reduced by approximately 19% with 5% CP (P > 0.05). Mean activity of liver cytosolic glutathione peroxidase was significantly increased by LPS injection, however it was reduced back to the value without LPS when the diet was fortified with 10% CP (P < 0.05). In groups with CP, a reduction in mean levels of serum protein carbonyl tended to occur in a dose dependent manner. Particularly with 10% CP, a reduction of approximately 89% was observed (P > 0.05). Overall results suggest that fortification of the atherogenic diet with CP may have potential health benefits for obese diabetes with high oxidative stress, by modulation of physical conditions, including some biomarkers of oxidative stress.

GARS스트레스지각척도 및 BDI우울척도를 이용하여 위암환자들과 위염환자들 간의 스트레스지각 및 우울의 정도를 비교하였다. 위암환자들의 50%, 위염환자들의 38%가 BDI우울척도에서 우울에 해당되었다. 위암환자군과 위염환자군 간에 스트레스지각점수는 유의한 차이가 없었다. 한편 BDI우울척도점수에 있어서는 통계적으로 유의한 차이가 없었으나 위암환자군이 위염환자군보다 더 높은 경향을 보였다. 위암환자들에서는 정신적 고통의 정도와 우울의 정도가 유의하게 양상관성을 보인 반면 위염환자들에서는 신체증상의 심한 정도와 우울의 정도가 유의하게 양상관성을 보였다. 즉 위암환자들의 우울은 신체증상의 정도보다는 정신적 고통의 정도와 더 밀접하게 관련되는 것으로 나타났다. 양군에서 각각 여자환자들은 남자환자들보다 스트레스지각이 유의하게 더 높았고, 연령은 스트레스지각과 유의하게 음상관성을 보였다. 결론적으로 동일한 장기의 기질적인 병리의 심한 정도가 스트레스지각 및 우울의 정도와 관련되지 않은 것은 위암환자들의 부정이 관련될 가능성이 있다. 따라서 위암환자들의 치료에서 정신사회적 접근 특히 정신과 자문조정활동의 필요성이 강조된다.

Purpose : The purpose of this study was to investigate the degree of post-traumatic stress disorder (PTSD) symptoms and the effect of PTSD on quality of life (QoL) among coronary artery disease (CAD) patients. Methods: The participants were 135 CAD patients who visited outpatient clinics in a university hospital in B city of Korea. Their PTSD symptoms and QoL were measured by structured questionnaires and analyzed with multiple hierarchical regression analysis. Results: Among the 135 participants, 20.7% were classified as moderate risk, and 3.7% as high risk for PTSD. PTSD symptoms were significantly higher in participants who were diagnosed with CAD within 6 months (t=26.02, p<.001). The physical component of health-related QoL was influenced by gender (${\beta}=-.25$, p =.003), recurrence of CAD (${\beta}=.21$, p =.008), and PTSD symptoms (${\beta}=-.33$, p <.001). The mental component of health-related QoL was influenced by religion (${\beta}=-.17$, p =.044), body mass index (${\beta}=.17$, p =.033), and PTSD symptoms (${\beta}=-.37$, p <.001). Conclusion: Patients who had had a CAD diagnosis for less than 6 months were found to be vulnerable to PTSD, and PTSD was found to have a negative impact on the physical and mental components of their QoL. It is necessary to develop an intervention program for the effective prevention and management of PTSD symptoms in patients with CAD.

This study was carried out to investigate the effect of Self-foot reflexology (SFR) on the hypertension of workers. The purpose of the research was to evaluate: levels of knowledge, physical and emotional condition, work stress and fatigue on the hypertension of employees in the workplace. Quasi-experimental study was designed in the setting of a nonequivalent control and experimental Group applied by the pre and post test. The total subjects undertaken in the study were total of 34 employees working in three companies in Seoul. The SFR program was consisted of 6 phases. There were 2 minutes for preparation, 4 minutes for slow down, 26 minutes for base reflex, symptoms of a disease reflex and excretion reflex stimulation. Finally, there was 20 minutes relaxation in a comfortable posture and drinking hot water after blood pressure was checked in the order. This program was running 55 minutes a day everyday three times a week during the entire 8 week course. The finding showed blood pressure was reduced significantly. Moreover, the level of total cholesterol. high and low density lipoprotein cholesterol, depression, work stress, and fatigue were decreased in the study. But, they were not statistically significant except as it related to Group comparisons in time. The level of state anxiety was statistically significant between 2 Groups, but not in the time comparison of both Groups. As a summary of the study results, the SFR program was regarded as contributing to the physical and emotional promotion of employees. It had partially increased body circulations of functional organ related to the SFR sites. And, it improved relaxation of physical and mental condition through energy movement 'Chi'. Therefore, the SFR technique should be considered as an effective skill of a nursing program. Furthermore, it can be newly adopted as a nursing curriculum as a part of alternative treatment. However, it still needed to testify its effects through the review study.
